baccoPipes, of which the following is a speciiication.

The object of myinvention is to produce a pipe that may readily becleaned, in which the ordinary screw for attachment of the mouthpiece tothe stem may be done away with, and. in which an enlarged smoke-chainheris provided between the bowl of the pipe and the mouthpiece, so that thesmoke is cooled before entering the mouth. of the smoker, and to thisend the invention consists in certain details of constructionhereinafter specifically set forth and claimed.

In the accompanying drawings, Figure 1 is a side elevation of the pipecomplete, and Fig. 2 is a vertical longitudinal section therethrough Thebowl is formed with a short stem portion A at right angles thereto,which is bored out cylindrically from end to end, and into which thesmoke-outlet from the bowl enters. The mouthpiece B has securelyattached thereto a stem C, which is reduced in diameter throughout. itscentral portion 0, and at the end adjacent to the mouthpiece is of suchdiameter as so closely it the cylindrical bore of the stem portion ofthe pipe, as shown at c, and the enlarged part c is cut away, as shownat 0 and at this point is formed the aperture 0 that leads into themouthpiece.

The opposite end of the stem has formed upon it a cylindrical portion orpiston D, that closely fits in the cylindrical stein portion of thepipe, and when the parts are in position the smoke-outlet a from thepipe-bowl opens into the cylindrical stein portion between the enlargedparts 0'' and D of the stem 0. Beyond the piston or disk D the end ofthe stem 0 is formed with a screw-thread to receive a cap-nut E, whichwhen screwed up firmly secures the mouthpiece and stem portion 0 inposition, the square shoulder or end of the mouthpiece being drawn upagainst the face of the stem portion of the pipe. By this constructionit will be obvious that in taking the pipe apart the piston D will,whenthe stem is drawn out, sweep or clean the cylindrical passage in thepart 13. Of course the stem part 0 may then be readily cleaned, as mayalso the part B, by passing a cloth or brush therethro ugh. The chambersurrounding the reduced. central portion of the stem 0 forms an enlargedsmoke-chamber,which gives the smoke an opportunity to cool to someextent before passing into the mouthpiece through the aperture 0 \Viththis construction a smooth and perfeet joint is always insured betweenthe mouthpiece and the stem portion of the pipe, and the difficultiesand objections attending the use of a screw or other form of coupling atthis point are obviated.

I claim as my invention A smoking-pipe consisting'of the combination ofthe usual bowl, a stem portion having a cylindrical opening extendingthere- GUSTAV STARK.
